There was a long-standing bicycle land speed record held by a doctor, who rode his 1-speed bicycle (the front sprocket was HUGE) behind a hot rod PU truck w/a big wind break strapped to it. He eventually did nearly 140 MPH. He was shown at speed wearing what looked like a cross between a wet suit and a speed skater's outfit in a Hot Rod mag (might have been a yearbook).

He's mentioned in passing HERE, where the record was broken by a newfangled bike.
